An apparatus is described comprising a piston assembly which consists of at least one piston rod being adapted to be reciprocated within a housing in a direction of reciprocation; at least one cylinder having walls in which at least one piston reciprocates forming at least one combustion chamber; a crank having an axis of crank rotation, a crankpin having a center; the center of the crankpin having a radius of crank rotation about the axis of crank rotation; at least one piston rod having a piston rod stroke length of travel and a center of midstroke position halfway between ends of the stroke length of travel; means for fastening at least one piston to at least one piston rod, wherein alternatingly the rod is driven by the piston and then the piston is driven by the rod; connector means adapted to be attached to the crankpin; the connector means being rotatably mounted to at least one piston rod; the connector means having a center of connector rotation; a resulting distance from the center of rotation of the connector means to the crankpin center being equal to the radius of crank rotation; the piston rod stroke length of travel equal to substantially four times the radius of crank rotation, whereby the connector means rotates with an angular velocity same as but in a direction opposite that of the crank.
